A Connection between Submillimeter Continuum Flux and Separation in Young Binaries

We have made sensitive 800-micron continuum observations of low-mass, pre-main sequence (PMS) binary stars with projected separations less than 25 AU in Taurus-Auriga to study disks in the young binary environment. We did not detect any of the observed binaries, with typical 3-sigma upper limits of about 30 mJy. Combining our observations with previous 1300-micron observations of PMS Taurus binaries by Beckwith et al. (1990) and others, we find that the submillimeter fluxes from binaries with projected separations between 1 AU and 50 AU are significantly lower than fluxes from binaries with projected separations > 50 AU. The submillimeter fluxes from the wider binaries are consistent with those of PMS single stars. This may indicate lower disk surface densities and masses in the close binaries. Alternatively, dynamical clearing of gaps by close binaries is marginally sufficient to lower their submillimeter fluxes to the observed levels, even without reduction of surface densities elsewhere in the disks.Comment: 12 pages, uuencoded compressed postscript with figures; Wisconsin Astrophysics 526; to appear in ApJ Letter

Mid- and Late-Life Divorce and Parents' Perceptions of Emerging Adult Children's Emotional Reactions

A paucity of research exists pertaining to the experiences of emerging adult children in the context of parental divorce. This study uses Paul R. Amato's divorce-stress-adjustment framework to organize a set of predictors that potentially influence parents' perceptions of their emerging adult children's emotional reactions to a divorce. Data come from a nationally representative AARP study, from which we analyzed a sample of 283 parents who experienced a divorce at age 40 years or older. Results indicate that parental gender, nature of contact with the ex-partner, divorce timing, time spent contemplating divorce, a history of parental divorce, and the reason for divorce influence parents' perceptions of their emerging adult children's reaction to the divorce. Implications, limitations, and future direction for research are discussed

Informing efforts to prevent family maltreatment among airmen: A focus on personal resilience

Family maltreatment is a serious public health concern within civilian and military populations. The U.S. Air Force Family Advocacy Program (FAP) delivers services to active-duty Air Force members and their families that aim to promote personal resilience and prevent maltreatment perpetration among those most at risk. Informed by family resilience and ecological perspectives, the purpose of this study is to empirically test a theory of change or conceptual model that could serve as an evidence-informed foundation for the selection of prevention interventions used by military and FAP service providers. A representative sample of 30,541 active-duty Air Force members from the 2011 Air Force Community Assessment Survey was analyzed, comprising participants who had at least one child and who were in a committed relationship. Structural equation modeling was employed to test the hypothesized model. Neighborhood safety was analyzed as a moderating influence. With a focus on personal resilience as an asset-based outcome, results indicated that personal resilience among airmen was positively associated with features of individual fitness, informal support, adaptive family processes, and unit leader support. Results also indicated that neighborhood safety significantly moderated associations in the empirical model

Confirmatory Factor Analysis of a Measure of Comprehensive Airman Fitness

The U.S. Air Force has committed significant resources to implementing policies and programs consistent with the Department of Defense\u27s concept of total force fitness. A 12-item measure of Comprehensive Airman Fitness was proposed and empirically examined, using component measures of mental fitness, physical fitness, social fitness, and spiritual fitness from the Support and Resiliency Inventory. Results confirm that the components of airman fitness can be conceptualized as pieces of a total fitness construct and that the measure is invariant across subgroups. Implications for policy and practice are discussed, and an agenda for future research is presented

A Measure of Comprehensive Airman Fitness: Construct Validation and Invariance Across Air Force Service Components

This article addresses the construct validity of an online assessment measure intended to reflect the biopsychosocial and spiritual fitness of U.S. Air Force (AF) members, defined as Comprehensive Airman Fitness. The analysis presented examines the extent to which this measure and the associated validation model are invariant across three AF components: active duty personnel, members of the Air National Guard/AF Reserve, and AF civilian employees. Our results indicate that total fitness (i.e., second-order factor), its four subcomponents (i.e., first-order factors), and the resiliency construct associated with role performance are invariant across service components at the configural, metric, and scalar measurement levels. Further, the strong positive association between total fitness and resiliency is statistically indistinguishable across all AF components. Limitations and implications are discussed

The Connection between Submillimeter Continuum Flux and Binary Separation in Young Binaries: Evidence of Interaction between Stars and Disks

We present 800 micron continuum photometry of pre-main-sequence binary stars with projected separations a_p < 150 AU in the Sco-Oph star-forming region. Combining our observations with published 1300 micron photometry, we find that binaries in Sco-Oph with 1 < a_p < 50--100 AU have lower submillimeter fluxes than wider binaries or single stars, as previously found for Taurus- Auriga binaries. The wide binaries and single stars have indistinguishable submillimeter flux distributions. Thus, binary companions with separations less than 50--100 AU significantly influence the nature of associated disks. We have explored the hypothesis that the reduction in submillimeter flux is the result of gaps cleared in disks by companions. Gap clearing produces the qualitative dependence of submillimeter flux on binary separation, and a simple model suggests that large gaps in disks with surface densities typical of wide-binary or single-star disks can reduce submillimeter fluxes to levels consistent with the observed limits. This model shows that the present submillimeter flux upper limits do not necessarily imply a large reduction in disk surface densities. Two-thirds of the young binaries were detected by IRAS, showing that most binaries have circumstellar disks. These fluxes place lower limits of 10^{-5} M_sun on circumstellar disk masses. The submillimeter fluxes place upper limits of 0.005 M_sun on circumbinary disk masses. Thus massive circumbinary disks are rare among binaries with separations between a few AU and 100 AU. Circumbinary disks are found around some close binaries.Comment: ApJ in press (Feb. 10, 1996). LaTeX, 35 pages, uses AASTeX macros.

The Willingness of Military Members to Seek Help: The Role of Social Involvement and Social Responsibility

Anchored in the social organization theory of action and change, we use data from a large sample of active-duty Air Force members to examine the direct and indirect influence of social involvement and social responsibility on willingness to seek help in times of need via trust in formal systems and informal supports. Group comparisons are conducted between junior male, junior female, senior male, and senior female service members. The key mediational path in the model for all groups is the connection between social involvement and willingness to seek help via trust in formal systems. These results can inform both unit- and community-level interventions intended to increase the likelihood that active-duty AF members will seek help in times of need
